Window folder and System Volume information too large.

I did google a few times but couldn't find a way to solve. I'm using Windows 7 pro x64 (I think I upgraded from windows 7 home edition). I had same problem last week but while I was cleaning out some stuff windows was updated so I had to restart....and then there suddenly was 17 gbs free space. But ever since last update my HDD is down to attachments.

I'm on laptop with followings:

ASUS N61JQ-X1 16-Inch Laptop
1.6 GHz Intel Core i7-720QM Quad-Core Processor
4GB DDR3
320GB HDD
Windows 7 Home Premium

I'm using TuneUp Utilities 2011 (luckily the new guys who took over and messed up TuneUp stuff decided not to mess with anything before 2012 version) with Avast. As you guys can see from my attachments, Windows folder and System Volume Information alone are taking 50+ Gbs. I'm also wondering if I need all these crabs with amd64-microsoft-naturallanguages-blahblahblah? I have 84000 files of these craps. I do keep it hibernation which is about 3gbs. I moved system restore point to external HDD so no back up whatsoever in C drive, all games except few, which are located in D drive, are located in external HDD.

Is there any way I can possibly clean up from windows and system volume information without harming my computer? btw, I didn't do a single format ever since I bought this computer because it still runs smoothly. The only thing that's bothering me right now is C drive space, and I don't want to format because I'm going to grab a new machine for programming at the end of the year (and for star citizen).

So yeah. Is there way to permanently free up to at least 10 gbs? That'll help me a lot with everything.

Thanks in advance!

Note: I see you moved System Restore to another drive, no idea how that affects the following! Follow it regardless.

Avast Bug

Avast sets System Restore disk usage % to 50.

You can try:
- go to control panel-> programs and features -> Avast -> change
- remove the component NG (down below).
- change % back to 10% (windows default) or whatever you like it
- restart
- check if % is what you set
- check restore points (seems this NG delete old restore points when run out of space)
- manually create a restore point if there are none
- open command prompt ->vssadmin list shadowstorage
- see how much space it takes.

You can also try uninstalling Grimefighter if above won't solve your problem.

For Windows folder:
Did you run Disk Cleanup yet?

alright my bad. I did research on how to change location of system restore point "again" because I wasn't sure if I really did or not. I did change back up location on D but things are weird....first of all, C drive's system restore protection is ON with current usage as 16 gbs (which is close to what I set 25% of the whole drive). D drive is OFF but has back up files in the drive.

Now I tried to uninstall that NG feature.....nope, it's not there. I'm using, as you can see, Avast Internet Security and apparently it's not included...

Is there way to check how many system restore points/back up files I have like I do with D drive? So that I can reduce my C drive restore points % to lower value? I could guess but since it's drive with Windows system I want to take it carefully.

Edit: I did disk clean up, fragmentation, boot scan and anything I can play with TuneUp Utilities to try to free spaces....which is failing.

You have Avast Secure Virtual Machines installed.
Avast has "renamed" this NG tool, making things confusing ...
Remove Secure Virtual Machines, or wait for Avast to fix it.

Avast NG = Secure Virtual Machines = Sandbox (as i understand it).

I don't use any of the optional "bloat" and don't have the problem others have.

I updated my copy-paste solution to include Secure Virtual Machines and Sandbox. - Thanks David

I have personally uninstalled that feature from a friend's PC and it was called NG (Programs and Features-Avast-change). I couldn't see anything similar inside the program itself but grimefighter and sandbox was configurable from within the app (no idea if it would have corrected the issue though).

Vaygr: Would you consider using Macrium free as your backup/imaging solution instead of Windows Backup? Seems many around here favor that one more than the built-in app.

Ok I uninstalled suggested Avast features which freed me about 3 gbs and also set system restore point for C drive down to around 10 gbs which gave me 8.3 gbs.....until today. Main problems are 1. Windows folder is too big (or is that normal?) 2. I'm loosing C drive day by day, sometimes hour by hour. It's keep decreasing without making any. It was 8.3 gbs yesterday. Today it's down by 300 mbs. And I don't remember making anything that's about that size yesterday. Is there way to see what was made recently?

on the other hand, my brother is keep saying I'm being hacked. I've been saying it's bs but....am I?

Did you run Disk Cleanup on C yet? Search for it in Start menu.

300 MB "may" be from temp files, cache or System Volume backing up some stuff, slowly filling the allocated space.

My Windows folder is 22 GB.

You can search for modified files from Windows Explorer, click search box and select Date Modified.
