System Restore Error 0x800700AA and Task Manager

Thank you for your response. Some of the common symptoms of (0x800700aa) are unfinished installation of Windows application, virus infections, inaccruate registry entries, corrupt system files, incompatible or outdated software or hardware, unfinished uninstalling
of some files, clashes between the automatic update error and the computer, installing of some corrupt or infectious apps or files, etc. In this case, we suggest to run a clean boot on your computer. Kindly follow the steps provided by
Stephanie Sal on this
link.

Regarding about the Task Manager concern. Malware may prevent opening of Task Manager. So you may want to clear your computer junk files and then run a full or deep scan with your antivirus or security software or Microsoft Security Essentials. If you're
done running those tests. We suggest to run DISM and SFC. By doing so, the task will scan for changed or misplaced files. If sfc discovers that a protected file has been overwritten or corrupted, it retrieves the correct version of the file folder, and then
replaces the incorrect file. Kindly follow the steps below to perform the task:

Run DISM and SFC

• Open an Administrator CMD window. If you can’t find a way, use these steps:
  • Press CTRL+Shift+ESC to open Task Manager.
  • Click File > Run New Task.
  • Make sure you have a check mark beside “Create this task with administrative privileges” .
  • Type CMD.
• Type the following commands at the CMD prompt:
  • dism /online /cleanup-image /restorehealth
  • sfc /scannow
• If neither command shows a good result, go to Reset your PC.

If none of the above options work, review the different recovery options available in Windows 10. The
“Keep my files” option should work – Reset your PC > Option > Keep my files.

If you're unwilling to reset the PC, you can try uninstalling the antivirus software, and do an in-place reinstall.

Should you need further assistance, feel free to get back to us.

Regards.

 

No restart button in task manager

another easy way to kill tasks, download and install Winaero Tweaker(free) and theres a setting to add a Kill non responding tasks using the desktop right click menu. When you place your cursor on the desktop anywhere and right click the option is at the top of the list, Very handy and you dont have to go through all those steps and well Winaero Tweaker has alot of cool Windows tweaks. Just posting a different suggestion, Im sure your ok with what was suggested here.

 

Task Manager not running


I have added a new task to the ones already populated which I suppose were in Win7
The new task or the present tasks are not running as there is no entry in the history or
recently run file
are there other steps necessary to get the new task manager to start up ?
