How to Repair ONLY Win 7 in dual-boot Win 7 and 10 PC? Both Pro 64-bit

I have a nice PC that dual-boots Win 7 Pro 64-bit and Win 10 Pro 64-bit.

I'd like to do a "non-destructive repair" of ONLY the Win 7 [probably by using the "upgrade" function of a Win 7 installation CD or img] but what steps should I take to make sure the Win 7 repair doesn't touch my Win 10 (and the ancillary partitions with the boot loader/MBR, etc.) and keeps my PC dual-booting?

Thanks.

 

Upgraded from Win 7 64 bit to Win 10 - was Win 10 64 bit automatic?

Please somebody help me out. I had Win 64 bit on my PC. It worked much smoother and faster than Win 7 32 bit. I later upgraded to Win 10; however, I was not given an option of 32 or 64 bit. Was it automatic? I think my sys is 32 bit. I also deleted
files enabling me to revert to Win 7 64 easily. If I have Win 10 32 bit, can I convert or upgrade to 64 bit? If so, do I need to revert back to 7 64 bit first or reinstall 7 64 back to get extra files I deleted first? Please inform.

Thanx, Miguel

 

Upgrade Windows 10 32-bit to 64-bit.

You have to do a "clean install" of Win 10 64 bit. There is no "upgrade" process from 32 to 64 bit.

Did you have Win 7 Home or Pro. There is no "free upgrade" from Win 7 Home to Win 10 Pro. You have to do that upgrade in at least 2 steps:

Win 7 Home to Pro to Win 10 Pro

OR

Win 7 Home to Win 10 Home to Win 10 Pro

The 32 bit to 64 bit upgrade is a separate additional step.

Run the WinVer command. What Version and Build do you have?

If you have Version 1803, many people have reported "accidental" upgrades from Home to Pro by MS. But that "upgrade" doesn't work!
