Will re-installing windows wipe out all my installed programs and files?
Even the System Restore seems to have corrupted one of my games and also MS Paint, I'm concerned what an entire re-install might look like.
A "clean install" will remove everything. It will be starting from scratch.
You can ofc, save your "files" to a USB stick or to a storage drive, so you don't lose those.
You can also export and save your bookmarks as well.
As mentioned above, assuming the problem is a Windows problem, and not a problem with any 3rd party apps or programs...
then an In-Place Upgrade is what you want.
Keep in mind, that an In-Place Upgrade will only fix Windows problems.
An In-Place Upgrade "compares" what is installed on the computer, with the Windows ISO image.
Then, it overwrites any corrupted Windows files, with clean copies from the ISO image.
This is how it "repairs" Windows while allowing you to keep your programs and personal files.
This tutorial will show you how to do a repair install of Windows 11 by performing an in-place upgrade without losing anything. If you need to repair or create a new recovery partition or having problems with the Windows 11 operating system on your PC, and the usual solutions will not fix it...

Here is the short version of the In-place upgrade tutorial...
DISABLE non-Microsoft:
a) antivirus software
b) firewall software
c) drive encryption software
Make a full OS backup with a program like Macrium Reflect or AOMEI Backupper Standard
Making a backup is optional, but always a smart move.
Macrium Reflect
AOMEI Backupper Standard (free)
Get the
Windows 11 ISO (Option #2), and save it to your desktop...
Right click the ISO image and choose:
MOUNT
Open File Explorer and you will see a new drive letter. It will "look" like a DVD optical drive.
Double click the new drive letter to open it.
Find
setup.exe and double click it to start the in-place upgrade.
Choose the
Keep personal files and apps option.
After it's all done... to UNmount the ISO image, right click the new drive letter and choose:
EJECT.
The ONLY thing you will lose is some of your personalizations.
Your drivers, programs and data will be intact.
=========================================================================
An In-Place Upgrade should take about 40-45 minutes.
If it doesn't solve your problem, then you can always do a "clean install" of Windows 11.
Generally, this is the order we do repairs. You only need to do any of these until the problem goes away.
1. SFC, then DISM... RestoreHealth <---- fixes only Windows problems
2. Repair install with an In-Place Upgrade <---- fixes only... bigger Windows problems
3. Clean install of Windows 11. <---- starts from scratch (even wipes out Daleks)
4. If the problem is a hardware problem... none of these will help.
NOTE: If the problem is caused by an infection, steps 1 and 2 won't help. Step 3 will remove most infections.
This is the reason we use backup software. Unlike System Restore, which "merges" the restore point with the Windows install,
restoring from a backup, "overwrites" the entire Windows install with your backup.
So... as long as your backup is clean... it will fix any software problems, including infections.
