How to delete windows.old folder?

People have been asking me, how can I delete the Windows.old folder in my C: drive after upgrading Windows?

A lot of people try and just right click and delete but this will only present you with aces denied issues. Well the best way to delete this folder is to use Disk Clean-up Tool by doing the following:

1. Start/All Programs/Accessories/System Tools/Disc Cleanup

2. When the dialog box comes up, select the drive that has the .old files on it and click OK

3. The system then scans for the files to be cleaned up and another dialog box opens with the selection.  Click on the button labelled Clean up system files at the bottom of that dialog box.

4. Another dialog box will come up, select the drive again that has the .old files on it.  The system will perform another scan for the system files that need to be cleaned up.

5. After scanning, another dialog box opens up and there you will find a list of check boxes.  Scroll through and check on the box labelled older versions of Windows and click OK.

Disk Cleanup

It will take about 10 – 20 minutes dependent on how big the folder is, but essentially that’s all you have to do.

Mailbag 23/09/2010 – Windows 7 Server Mode

The main problem I have been hearing this week is people using windows 7 as a file server or people trying to access their windows 7 machine in some way from a Windows XP machine. This is fine if the windows 7 pc gets regularly restarted, the reason for this, not fully known to me, is that windows 7 has an issue with memory allocation to system non-paged pool.

You may be getting this error log issued to your event logs:

Source: srv
Event ID: 2017
Level: Error
Description: The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.

The fix is just a simple registry change below:

Set the following registry key to ‘1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

and set the following registry key to ‘3′:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

This should definitely sort out the problem, if not please let me know.

I found a fix many months ago unfortunately I am unsure where I got it from, so I am not able to give recognition to the correct person.
