I was looking to regain some space on my laptop hardrive and started looking at the size of different folders.I noticed that my windows folder is 16.8 gb.
I believe it should only be about 3 -4 gb. looks like 2 folders in windows (winsxs more than 4.17gb) and system32 (more than 1 gb ) are pretty big but I dont know what specifically is doing it.I use ccleaner all the time so I dont think I've got temporary files not being deleted. I'm not sure what to delete
If you turn off system restore you will see you re-gain several gig of hard drive space. If you desperately need the space leave it turned off but you MUST remember you will not be able to roll back your system if you have any problems.
