[lovingGamer]

Okay So i installed Windows 10, in Local C: disk i see windows folder and windows.old folder 

 

Is it possible to delete windows.old folder (It's taking space!)

[AlwaysFSX]

Yup.

No not while your using Windows. Have to do a clean install. In pc settings reset PC.

wait what?! I don't have windows 10 DVD

Windows.old is simply your previous Windows install. Just make sure you've retrieved all your files you don't want to be thrown out from your Win7 or Win8.1 install.

It's perfectly fine to do so. 

 

Edit: 

Found Microsoft's process to deleting Windows.old. 

 

1. Open Disk Cleanup by clicking the Start button . In the search box, type Disk Cleanup, and then, in the list of results, click Disk Cleanup.

   If you're prompted to choose a drive, click the drive you just installed Windows on, and then click OK.

2. In the Disk Cleanup dialog box, on the Disk Cleanup tab, click Clean up system files.

   If you're again prompted to choose a drive, click the drive you just installed Windows on, and then click OK.

3. Select the Previous Windows installation(s) check box, and any other check boxes for the files you want to delete, and then click OK.

4. In the message that appears, click Delete Files.

That's for Win7, but should work just as well for Win10.

Windows.old folder can be safely deleted once you are sure you have all the files you need from your old install of Windows 7/8.1

Like me, sometimes it has some .dll, and files that windows thinks that are running, so you can't delete it. IK I can't without doing some stuff, but most likely you can.

Just do a clean install.

I just reformatted after I upgraded, it's easier but requires a USB or DVD thats been created with the Media creation tool

Thanks man!

[clementk]

if you want to uninstall windows.old its easy go to "This PC" or "my Computer" then right click on C:\ and go to Properties>Disk Cleanup  then there is a button that says clean up system files.. after clicking that check the list and you will see old windows tick it and let it run

Just do a clean install.

Upgrading pretty much is, it just keeps your previous version of Windows, you still need to install all your drivers, programs and the such. 

 

I don't see any files that i would want in that file..

If you're sure there isn't anything, than go ahead with the procedure I quoted in my first post. 

 

Thanks man!

No problem mate

you can also remove ols update files here its a good place to check every month if you have windows on SSD with low space

[Giddyguy]

Just run disk cleanup and select previous windows installations if you don't whant to do a clean install.

A upgrade install IS NOT a clean install.  It will still use some old Windows files, as well as it doesn't touch anything else.  So ALL of the problems that you had before, WILL still be there.  Not to include other potential compatibility issues, WITH more problems of upgrading vs being able to cleanly install.

Hmmmm, I was fairly certain that it just put your previous install into an easily accessible folder. Didn't know the current install still used files from the previous one. 

Well, thanks for the clarity.

It only just removes the Windows.old folder, doesn't do anything with the partition.

Well, not just reusing files and settings it doesn't touch your programs...  And 99% of problems you have with Windows is because of other programs interfering.  And little do people know, most programs will install differently based on what version of Windows you're running.  For example, when PhysX first came out for Nvidia you could install a game in a computer with a AMD video card and get PhysX working on a AMD video card.  But, now most games wont even install the PhysX component of the game in a computer with a AMD video card.  So it, now, would require you to have a Nvidia video card installed in the machine when the game is installed.  I know this is a hardware change versus a software change, but the same basic principle applies (that and with this being a gaming community I feel like this comparison is easier for people to understand).
