In the past, I wrote an article on Automating Disk Cleanup, this article is for users who still want to manually run the Disk Cleanup Wizard which you can find by navigating to: Start -> All Programs -> Accessories -> System Tools -> Disk Cleanup.exe
The Screencast
I have produced my very first Screencast for this How To! View the Disable Disk Cleanup Wizard Compression Calculation Screencast!
What This Does
This Registry Hack will disable the Disk Cleanup Wizard from calculating the space that could be saved by compressing the drive, which, if you have a large drive or a couple of drives, could take a while. It’s a time saver: it skips the calculation time and goes right to the dialog where you can choose what to clean.

Open the Registry Editor by hitting the Windows Key+R and typing: regedit
Navigate to this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Explorer\VolumeCaches\Compress Old Files
In the right panel, double-click the (Default) key. Clear the text in the “Value data” text field.

Click the “OK” button and close the Registry! The next time you run the Disk Cleanup Wizard, you will jump directly to the Disk Cleanup dialog!

Congrats on your very first [screen|pod]cast
Very useful, I hated how long Disk Cleanup spent calculating the compression time, since I never wanted to compress anything in the first place.
Thanks! Did you enjoy it? Should I do more screencasts? You should really check out my post on Automating Disk Cleanup - you can do it with one double-click or set the Task Scheduler to do it for you!
Did you enjoy it?:
Yep, well done.
Should I do more screencasts?
:
Sure, definite, why not? I would just standardize what term you are going to use, I think in the “screencast” itself, you call it a “podcast” - to me, its one and the same, but just for the sake of organization, you may want to standardize them as the “Samanathon Podcasts” or the “Samanathon Screencasts” - your choice of course
True, I actually did produce a podcast from this screencast, but I’m having issues submitting them to iTunes….
Way cool Saman!!!!
Very informative, also made it look very simple.
Nice to hear your voice too!
Looking forward to more screencasts!
Thanks bud! I try to make these as simple as possible - because they are!
from now on i’ll be using about 80% of your posts as my official to-do list
I’ve always turned off “automatically detect when diskspace is low” because my disk space is always low and disk cleanup took forever to run!
very useful. when I haven’t had a disk cleanup in a long time it takes a while to calculate.
Do you know if default value is the same for every computer? Just in case I ever want it back, which I probably wouldn’t?
Yes, the value is the same for every computer!
Nice one Saman!
Thanks for making it easy. Great screen shots by the way!
Regards, Don.
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!
Great hack! I maintain 5 Windows PC for my family home network and this trick has saved me a ton of time. Between this and Auslogic’s Defrag utility my monthly maintenance time has gone way way down!
Thanks for real time saver (which should be an option, or self learned, if MSFT gave a darn about their customers time).
I’ve tried several utilities, and now I’m using Junk Files Cleaner

It might be useful when pc getting extremely slow.
