CCleaner - short form for Crap Cleaner.
So should i go with this option on not ??? You being sysadmin know better. Please suggest.
Go to Computer Management and see if you can see a partition which is at the starting of the disk and doesnt have a drive letter assigned and has a name like restore or do not erase or system. It wont be NTFS too. If you have that restore will work. Or else erase it by my way 
Are we talking about restoring? 
OP u must be daft trying to use that useless/complicated feature! Just format the whole hdd, make 20GB partition for OS and be happy forever!
use these settings in Ccleaner
Try DiskMax as well.
I use ccleaner..pretty good..
I cannot do formatting and all. It is a company laptop. I just want to do a clean uninstall of everything.
ccleaner -the best by far
just shred your hard disk, using a good wiping toolā¦ chances of what youāve deleted using the recycle bin can be recovered easilyā¦ so chances of ur personal stuff being accessed are highā¦
simpleā¦ CCleaner
If u want to un-install everything use revo uninstaller (freeware), use its advanced feature that ādeepā cleans everything! Ccleaner is good for cleaning, revo for un-install. Hope it helps.
mine was 20gig fat32 partition with factory oem image
CCleaner inspite of being a freeware, offers a whole lot of options ! 
Op u tried revo???
I try to use freewares as much as possible, recuva, ccleaner, speccy, defraggler, these are great tools, very light, however revo is best when it comes to un-install anything
Ccleaner all the way man!! trust me its the best
spybotsd is best
+1. for CCleaner itās a very good App.

CCleaner is both free any good software. Alternatively you can try Privacy Guardian
Advanced system careā¦ Very very goodā¦ My 2 year old lappy vomited out 2 gigs of hidden, useless filesā¦
And, the free version is itself enuf. You will find the link to this software in a previous blog post.
TRUST MEā¦ BETTER THAN CCLEANER AND DISKMAX
