Read about what Safe Mode is for. How to start your computer in Safe Mode and fix your PC using it... Windows Safe Mode is an essential built-in tool. On computers infected with malware or crashing due to driver errors, Safe Mode may be the only way to start.
Safe Mode starts your computer with the minimum required set of drivers and services. All third-party programs are disabled, and even system tools are limited to only the required set of functions.
Safe Mode is a great way to get rid of malware blocking your computer from booting or working. It also provides an environment where you can roll back system or driver updates, clean startup, remove recently installed programs, or diagnose and troubleshoot Windows.
Content:When can Safe Mode help?
During normal startup, Windows loads all system services, installed hardware drivers and programs from startup. In Safe Mode, the system starts with a standard video driver, which provides a low screen resolution and does not affect hardware support. Windows starts only with the services necessary for the system and disables the startup of third-party programs.
If your computer reboots cyclically, freezes during boot, displays a BSOD error with a blue screen of death, or the system boot is blocked by a banner of a ransomware virus, then Safe Mode will be an excellent solution for diagnosing and treating these problems.
How to start your computer in Safe Mode
Your Windows 10 PC will automatically start in Safe Mode after 3 unsuccessful boot attempts in a row. But you can force Safe Mode. ... To start Safe Mode in Windows 7 or 8, you need to hold down the Shift key while the system is rebooting.
How to fix PC in Safe Mode?
After starting Safe Mode, you can perform a number of common system maintenance and troubleshooting tasks:
Search and remove viruses... Use an antivirus to scan your computer and remove malware in safe mode. Malware runs in the background and interferes with the system and antivirus. A virus that does not allow itself to be removed normally can be removed in a safe mode. If you don't have an antivirus yet, you can download and install it. Windows 10 comes with a free antivirus built-in to help you find and remove a virus.
Launching System Restore... If yesterday your computer worked fine, but as a result of changing settings or installing new drivers or programs, there were failures - use restore points. Windows Automatic Updates is usually turned on by default on most computers. Sometimes such updates lead to blocking the PC boot, the system reboots cyclically or gives an error and a blue screen of death. Often, booting into Safe Mode and rolling back to an earlier successful system configuration will completely fix the problem.
Removing recently installed faulty software... If the installation of the program blocks the start of the system or results in a blue screen error, you can uninstall it in the control panel. Such errors can be caused not only by programs that start automatically at system startup, but by software that constantly monitors the availability of updates on the Internet.
Removing or updating drivers... Automatic driver updates can also lead to system malfunctions. In safe mode, most drivers will not start or are replaced with less functional but more stable versions. A video or sound card driver can often be the cause of a crash. If you or the system has automatically updated the driver to a faulty version, roll back to the previous version or use the driver from the official website of the device manufacturer.
Determining the cause of the failure... If the computer does not start in a non-normal mode, not in a safe mode, then most likely your hardware is malfunctioning. In this case, it is worth turning off all third-party devices and restarting. Ideally, you should leave only the processor, memory and hard drive with the system. Then reconnect devices one at a time and restart to detect the problem. If you get a BSOD error during normal startup, use the Event Log and System Stability Monitor for more information and recommendations on how to fix the problem.
Reinstall Windows
Often times, finding and solving a problem leading to a system crash is not justified in terms of the time spent. A faster and easier solution would be a clean install of Windows.
Of course, reinstalling Windows will result in the loss of your personal files, so make sure you have a backup. Windows 8 or 10 provides an alternative to reinstalling - resetting your computer. With this, you can keep your personal files.
If after that your computer is still unstable, then there is a hardware failure in your computer. To continue working with the PC, it is necessary to identify the defective part and replace it.
Windows Safe Mode is a very convenient and necessary tool. On computers that are infected with viruses or have problems with hardware drivers, Safe Mode may be the only way to fix the problem with your computer.
Booting Windows in Safe Mode does not load any third-party software or drivers, so it is more likely that the boot will succeed and you can fix the problem in Safe Mode.
In theory, your computer should start Windows Safe Mode itself if a failure occurs during startup, however, sometimes you need to manually launch Safe Mode, which is done as follows:
- IN Windows 7 and earlier versions: you must press F8 after turning on the computer, as a result, a menu will appear in which you can choose to boot in safe mode. More details about this in the article.
- IN Windows 8: You need to press Shift and F8 when turning on the computer, but this may not work. In details: .
What exactly can be fixed in Safe Mode
After you have launched Safe Mode, you can perform the following actions with the system to correct computer errors:
- Check your computer for viruses, perform virus treatment - very often those viruses that the antivirus cannot remove in normal mode are easily removed in a safe way. If you do not have an antivirus, you can install it while in safe mode.
- Run System Restore- If your computer has been running stably recently, but now it starts to crash, use System Restore to return your computer to the state it was in before.
- Remove installed software- if problems with starting or running Windows began after some program or game was installed (especially for programs that install their own drivers), a blue screen of death began to appear, then you can uninstall the installed software in safe mode. It is very likely that the computer will boot normally after doing this.
- Update hardware drivers - Provided that system device drivers cause system instability, you can download and install the latest drivers from the official websites of equipment manufacturers.
- Remove banner from desktop - Safe mode with command line support is one of the main ways to get rid of SMS ransomware, how to do it is described in detail in the instructions.
- See if crashes occur in Safe Mode - if during a normal Windows boot with a computer problems - blue screen of death, automatic restart or similar, but they are absent in safe mode, then most likely the problem is software. If, on the contrary, the computer does not work in safe mode, causing all the same failures, then there is a chance that they are caused by hardware problems. It should be noted that normal operation in safe mode does not guarantee that there are no hardware problems - it happens that they occur only when the equipment is loaded, for example, a video card, which does not happen in safe mode.
Here are some of the things you can do in Safe Mode. This list is far from complete. In some cases, when resolving and diagnosing the causes of the problem that has arisen takes an unacceptably long time and takes a lot of effort, reinstalling Windows may be the best option.

Errors when installing and uninstalling programs in Windows Safe Mode
If Microsoft's remedy has been applied and you still unable to uninstall the program, or some of the recently installed programs were registered in startup and prevents the system from starting normally (more about managing startup here: Startup. Adding Applications to Windows Startup), then you can try uninstall the application via Windows Safe Mode... This method is also useful in cases where the software developer himself recommends uninstalling the program in Safe Mode.
What is Safe Mode, all the ways to start the system in Safe Mode, the nuances of entering Safe Mode for Windows 10, differences in actions for previous versions of OS, Windows 7 and Windows XP, are discussed in the corresponding article: Windows Safe Mode. Safe mode... As part of the current post, we will not dwell on this in detail.
Well, we entered Safe mode, open the menu Programs and Features in Control panels Windows, we find there the application that we want to uninstall, click the Uninstall button and ... we get an error with the following content:
Unable to access the Windows Installer service. The Windows Installer may not be installed. Please contact support for assistance.
Moreover, if we try to start the Windows Installer service manually, we will get another error
Error 1084: This service does not start in Safe Mode
Troubleshoot Windows Installer startup errors
To start Windows Installer service, you need to make changes to the Windows registry.
We open windows registry editor
- Run the utility Execute going to Start - All programs - Standard(in Windows 10, the utility Execute is in the directory Service), or by holding down the keys on the keyboard Start(on some keyboards it is marked as Win) and R
- In the window that opens, type in the regedit command
and press the key Enter
In the registry editor, go to the following branch:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ SafeBoot \ Minimal \
If you will be working in safe mode with loading network drivers, then further actions need to be done on the branch:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ SafeBoot \ Network \
Here, on the left side of the registry editor, you need to create another section, calling it MSIServer
In the created section, on the right side of the registry editor window, for the created string parameter (add a new string parameter if it does not appear automatically) in the Value field, write Service
We save the changes and close the registry editor window.
Now you can start Windows Installer service... This can be done in two main ways, which we will consider below.
Starting the Windows Installer service from the command line
Opening the command line:
In the opened console, enter the command
Net start msiserver
And press the key Enter... The console will give you a message that the service has started successfully.
You do not have to enter the command manually, but simply run the previously created bat-file, which is attached to this article: msiserver_start You can read more about body shirts and how to write them yourself in the post Batch files (bat, body shirts) Windows
Launch Windows Installer from the Services menu
Open the menu Services on Windows:
- Right-click on My Computer (in Windows 7, the explorer is simply called Computer, in Windows 10 - This computer), here we select the Manage item (in Windows 10, this item is located along the Advanced - Control path). Now open the menu on the left Services and Applications and click on the Service option.
- Either we follow the path Start - Control Panel - system and safety - Administration- Services
That's all. Now you can safely remove any application in Windows Safe Mode using both third-party uninstallers and the standard utility Installation and removal of programms in the Control Panel.
Not infrequently, when trying to uninstall a program, users are faced with the fact that the program is not uninstalled. When trying to start uninstalling a program through the Control Panel, the user receives an error that interrupts the uninstallation process. Then the program remains on the computer.
If you also do not know how to uninstall a program that does not uninstall, then this article should help you. Here we will look at three simple and effective ways to solve this problem.
Method number 1. Stop all processes associated with the program.
If the program is not removed, then, most likely, it is currently running. To stop the program, open "" (for example, using the CTRL + SHIFT + ESC key combination) and go to the list of processes. In the list of processes, you need to find those processes that are associated with the program and stop them.
If you have Windows 8 or Windows 10, then you need to right-click on the process that you want to complete, and in the menu that appears, select "End task". In Windows 7 and older versions of Windows, the menu item you need will be called End Process.
After all processes associated with the program have been stopped, you need to try to uninstall the program again. If this method did not help to uninstall the program, then try restarting your computer and try again. Perhaps you have something stuck and thereby blocked the uninstallation of the program.
Method number 2. Use a special program to remove programs.
If the program is not removed even after a reboot, then you can try to uninstall it using a special program. The most popular program of this kind is. This program allows you to remove any other programs. In this case, removal is possible even in cases when the uninstaller does not work or the program is not displayed in the control panel.
Using Revo Uninstaller is easy enough. First you need to run this program and wait until it scans your computer and displays all installed programs. After that, you need to right-click on the program that you want to delete and select "Delete".
After that, a window will appear in which you need to select a method for uninstalling the program. Moderate will work in most cases.
Here you can click on the "Select all" button and confirm the deletion by clicking on the "Next" button.
Method number 3. Uninstall the program through safe mode.
If none of the above helps to uninstall the program, then you need to boot the computer into and try again.
In safe mode, only the main components of the operating system are loaded; other programs that may block uninstallation are not loaded. Therefore, in safe mode, the deletion should go smoothly.
Hello dear readers of the blog site. Today is a short article on the topic of the windows operating system, or rather, how you can remove unnecessary programs in Safe Mode... This can come in handy in some cases. For example, as in mine, when the Windows operating system on my computer stopped starting normally after installing one program.
Recently, after installing the driver for the USB dongle, my laptop, when booting in normal mode, began to issue Blue screen of death or simply BSoD. Of course, you could not bother, and type in a search engine for computer repair in Lyubertsy, find some company and for 500 rubles they would fix everything. But I took a more difficult path and decided to figure out what was the matter myself. I'll tell you right away what is on my laptop windows 7 and all screenshots in the article and instructions are given specifically for this operating system.
When I tried, windows started up without any problems. Attempting to roll back the system to a restore point before installing the driver was unsuccessful. After booting in normal mode, the blue screen fell out again, and when booting in safe mode, a message appeared that the system restore could not be performed because it was not possible to access the system files.
Next, I just tried to remove the ill-fated driver. But when I tried to uninstall the driver from Safe Mode, I got the message “Unable to access the Windows Installer service. The Windows Installer may not be installed. Please contact support for assistance. "
On an English version of Windows, this message will look like this: “The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance. "
When trying to start the service Windows Installer(in the service management console it is called Windows Installer) also got out an error message (The service could not be started and this service does not start in safe mode):
As it turned out later, you can start the service by editing the system registry. In order to avoid the above listed problems and make the WIndows Installer work in safe mode, I have prepared a short instruction:
1. Start the registry editor regedit.
To do this, in the menu "Start" in the file search bar, enter regedit and run the found file, which will be displayed at the top Start.
2. We make changes to the system registry.
To do this, open this section using the tree menu in the left pane of the editor:
And create a subsection here with the name MSIServer... To do this, right-click on the name of the section and in the menu that opens, select "Create -> Section".
And as the name of the created subsection we write MSIServer.
Meaning "Default" make equal "Service"... To do this, double-click on the parameter name. A window will appear "Changing a string parameter"... In this window in the field "Meaning" enter the desired value.
As a result of editing the system registry in the section HKLM \ SYSTEM \ CurrentControlSet \ Control \ SafeBoot \ Minimal \ we should have a subsection MSIServer whose parameter value Default should be equal Service.
3. Starting the Windows Installer service
After the above steps, you will be able to start the Windows Installer service. There are several ways to start a service. The easiest way is to type in the command line net start msiserver... In case of successful launch, a message appears in the command line that "Windows Installer service started successfully".
Or you can use the service management console. To do this, right-click on the icon "My computer" on the desktop or in the menu "Start" and press "Control".
This will open a window "Computer Management"... In the left pane of the window, in the menu, go to the section Services and Applications -> "Services"... A list of services will open in the right pane of the window. We are looking for a service in this list Windows Installer, right-click on it and press "Run".
If you did everything correctly, then the service should start and there should be an opportunity uninstall programs in safe mode.
I will add that in this way you can start almost any service in safe mode. That's all, until we meet again on the blog pages.
