Should I reinstall windows ?

[Age of 9394]

My computer had a virus, but I succeed clean the virus. (I think)

So should I reinstall windows, to make sure everything safe

Also, how to start windows 10 safe mode with out any program like system configuration or shift + restart, and Windows 10 disk/flash drive

For example, using F8 like windows 7 to start windows safe mode. Do windows 10 have that ?

why are there so many blank lines in task manager?  There shouldn't be any afaik.  Generally it would never hurt to just totally reformat after a proper infection.

i ALWAYS Format after virus is detected, just to make sure

 

it isnt a big deal to format anyway especially if u had split ur partitions or windwos drive from ur actual stuff x)

 

should be like 20-30mins and ud have everything back + drivers installed o,o

To get to the F8 menu on UEFI systems, you have to hold Shift, while clicking Restart in Windows. It will allow you to choose Advanced Options there. 

 

Reinstalling Windows is a pretty good idea, given how easy it is (aside from reinstalling apps), and it only takes about 10 min to install. Make sure you get latest version of Windows USB from https://www.microsoft.com/en-au/software-download/windows10 (use the Media Creation Tool, since it has all updates/editions and formats your drive properly). 

Windows installation takes less than 10 minutes on most systems (from USB insertion, to being at the desktop).

Can't open anything on windows because it is too slow and the virus is stopping me to open stuff when my pc had the virus. I can't even press the start key to restart.

This is why I am asking, it windows 10 have any key like windows 7 just press F8 to the start safe mode

Can you do it from the login screen (before you log in)?

 

F8 still works, but only if it's not using fastboot. If you shut down normally, fastboot will be enabled on next boot.

So, to temp disable fastboot, and allow F8 to work, just restart from Windows, or force shut down using your PC's power button. F8 will then be functional on next boot. 

 

Alternatively (and perhaps more reliably), you can go to your BIOS boot menu, and choose Windows Boot Manager. That will launch directly to the F8 menu. 

 

 

Note that these two methods only apply if you have a properly-set-up UEFI-based system. If you don't, F8 should work as it did in Win7.
