Is it safe do delete Windows.old folder

[alexham36]

My Win10 (upgrade from Win7) crashed last night and I had to reset the OS. I now have a folder Windows.old and I am wondering if it is safe to delete it to free up space/

It's there so you can retrieve personal files, but it saves a whole lot of other unnecessary garbage too
navigate to users/YOUR-username to make sure there's nothing in there you might want to keep

All the rest is junk and can be deleted

Thanks, Mikkh. I tried but too many files are the "property of" TrustedInstaller and changing the ownership would have taken many hours because I don't now how to do it expect individually. But, surprizingly, Puppy has not heard of this impediment! It took a long time, but I have managed to delete most of the old files and I am now running Win10 on 17GBs and that includes OpenOffice, Thunderbird, Firefox, Irfanview, Foxit Reader and Epson printer/scanner software.

Do you think it would be worth setting up a Restore Point now that all is working well? Does that work well in your opinion and how much HD space will it take?

Thanks again,

Alex

It's worth looking how much space is currently used - mine was 5 GB+

I deleted the lot and created a new one - 45 MB!

Type 'system restore' in the search box pick 'create a restore point'

In the window that opens pick configure then 'delete all restore points' in the next window that opens and press ok

Then create a new one in the first window


Does it work well? It can help you with minor problems, but when you're really in the mire, it's a bit hit and miss in my experience
You can set a maximum size for it to keep usage down, I'd be tempted to set it to 1 GB in your situation
