After I experienced crash, which was caused I thing due to bad RAM which I replaced then,
I couldn't repair windows to the state it was.
I have problems with windows explorer,
it reopens, almost every time I open WE and then closed it, it reopens again to the same folder.
For example if I click in utorrent 'open containing folder' it will open it and then refresh it to the begining of the file list. When I close the window, it will reopen again.
Also, I cant force WE to remember settings for each folder, (like I used to before crash). In all folders, files are listed as 'date modified' if I try to change to different settings it will not remember, even if I click back and return to folder, it already change to default 'date modified'.
Another thing, icons on desktop are largest, I can decrease the size of icons, but they resset to largest every time I reboot.
I tried SFC /SCANNOW, doesnt find any errors.
Also scanned with kaspersky boot CD, no problems found.
I was thinking to recover some files from old backup, and to replace existing files, but which files should I recover?
What would be the registry keys that I should look for in order to fix this?
Any system restore points before this crash (issue) can go back to, as this will replace registry files ?
Tried that but it was corrupted.
Any other way?
Then i would try this first and see if it helps.
Open (Admin) Command Prompt by right right clicking the Start Menu, copy and paste this into open command prompt and press enter, let it finish
sfc /scannow
Same open command prompt, copy and paste this and press enter, let it finish
Dism /Online /Cleanup-Image /RestoreHealth
After both complete reboot (restart) PC.
Have any external Devices hooked up, USB Drives ? Any added folders made from software in File Explorer, some external device or software maybe doing this.
I already wrote in a first post that "I tried SFC /SCANNOW"
Tried DISM... problem is still the same.
What are the registry keys that are for this settings in windows explorer, that I explained.
Which key is for desktop icons size? So if I delete that key/import correct settings, maybe it will solve the problem.
Sometimes you need to run SFC and DISM few times and reboot afterwards to fix corrupted files. Seems to me if system restore was corrupted then there is corruption in the operating system files, along with some of issues you wanted to try to fix by using registry edit, would not advise editing registry and without backing it up first. I do not know of any registry edits you can use and i believe you mean to fix settings in folders to remember last used options. Most of these settings are right there by right clicking (context menu) and above in the menu. Can look at Folder options in control panel, try resetting it or check some settings there.
Your biggest issue involves File Explorer reopening after closing and right now should be your biggest concern and a regedit will not solve this. Why it is happening, i am not sure as it can be due to another software on system or device and or device driver. You even stated you still had issues even after the crashes from RAM, basically RAM was not only issue then and now.
Suggest trying File Explorer in Windows safe mode and see if it happens there, if not then some of the issues i just mentioned can be the problem.
Safe Mode - Start Windows 10 in
