C: Drive almost full after Win 7 Reinstall

See if this helps:
Disk Cleanup : Extended

Then, if you still need assistance, post information about your drive(s)
See: Disk Management - Post a Screen Capture Image

Thanks

Too bad the extended disk cleanup did not reclaim any space.
I should have asked for a screen shot, so I was sure everything was marked - did you select everything or did the image in the tutorial guide you?

That is one perfect picture. This way the drives are connected makes it a bit hard to read, that and I only speak English.
Neither one is a big concern to me, I can determine the information from the column position and deduce that Ensisijainen osio means Primary partition. If I get stuck, there's always Google translate.

If I get really stuck, I'll just ask someone who knows the Finnish language. You would be my first choice

so the 100 Mt partition is:
System, Active, Primary partition

and C: is:
Boot, Page File, Crash Dump, Primary partition

That looks fine if I adjust for Google, just thought I'd check those partition flags.

Try running another good tool, cCleaner
Piriform cCleaner Download page
Press the Download button under the FREE version
Alternate download method: Piriform cCleaner Download button

Select Run on the download action bar

During or after the install

• Do NOT accept a free trial if offered
  
  
• Do NOT install cross marketing software if offered
  Remove the checkmark from boxes for any additional software (usually a browser or toolbar such as Ask or Google)

Launch cCleaner and look at the options selected. If Windows.old is an option, make sure that is selected. The reset of the defaults are good enough for the first time.

click analyze and then clean.

Don't bother with any other features until you need them, you're only using cCleaner to find disk space. That is the default feature shown when you launch the application.

Depending on the amount of space reclaimed, I might ask you to run Disk Cleanup again using different instructions and posting screen shots.

Hello Zakaln!

This could also be a System Restore point situation, where too much space is being saved and occupied by the System Restore data.

Do a Disk Cleanup on your drive, remove all but the last restore point. Clear the Temp folder. Then go into Restore settings and shrink the amount of hard drive space that's allowed to be used for restore points. If the space allowed is too big, your drive will be shrinking really fast from free capacity and would constantly be performing processes. Normal setting is to use about 5% of space.

Check your programs, if there's something that's acting on the background that would take up such large percentage of active time and temporary files.

Defragment your drive and restart the PC. See what happens.

Hope this helps too!

CKWD reminded me of another tool; Temp File Cleaner - it is very good and very fast

Restart your machine in case there are any system operations pending

Click here to download Old Timer-TFC.
>> save the application to your Desktop.
Old Timer-TFC is a standalone application, there is no install.

Save your work and close all open windows.
TFC will close ALL open programs including your browser!

Right click, run as administrator TFC

Click the Start button to begin the cleaning up temporary files and folders.
Do not work on other things while TFC is running - most applications use some sort of temporary files. Just let TFC run by itself on the machine until it completes.[/COLOR]

Moi Zakain, terveisiä sinne koti-Suomeen :).

There are several reasons why disk properties (your screenshot #1 in original post) and Disk Management (screenshot #2 in same post) show different figures for disk usage. For instance the hidden system folder System Volume Information contains data for stored restore points which is not shown as used disk space in Disk Properties but will of course be counted in disk management. Also the page file is not counted as used disk space in Disk Properties.

I suggest you download and install the WinDirStat tool, it shows you exactly what is taking place on your hard disk.

In the future, to save some space you could change the maximum size of Recycle Bin and stored restore points (screenshots from English Windows, I'll boot up a Finnish one and add Finnish screenshots in a few minutes):

Check your C: drive with WinDirStat and come back to tell us what it revealed.

Good to know you found the culprit :).
