Tsfltmgr.sys is the system file of qq computer housekeeper. Recently, when win7 users started their computers, a windows startup manager interface popped up, prompting that windows failed to start, and there was an error in the file of tsfltmgr.sys. What should I do if the file of tsfltmgr.sys appeared when win7 system computers started? Next, I will introduce the solution to the file error of tsfltmgr.sys when the win7 system computer is turned on.

Solution:

1, as shown in the screenshot: The system can't verify its digital signature, so the operating system can't start normally.

2. First, search this TsFltmgr.sys file to see which fairy it is. It turns out that this is not a system file, but Tencent's' computer housekeeper file'.

3. Because you can't enter the normal operating system when you start the computer, press F8 to try to enter the safe mode. In safe mode, programs unrelated to the system will not be loaded, so many fault factors can be eliminated.

4. You can click Uninstall Computer Manager in the Start menu. If the menu is not available, you can uninstall it in the control panel.

5. Use the Windows+E shortcut key to bring up the resource manager and open the control panel.

6. Control Panel → Program.

7. Program → uninstall program.

8. Right-click the computer housekeeper → click → Uninstall immediately in the pop-up dialog box.

Security software has great authority, and once it is abnormal, it will not be able to enter the operating system.
