[FIX] Windows 7 Deletes All System Restore Points Upon Reboot

Recently Microsoft identified a bug in Windows 7 and provided a solution for it. Following are the details:
Upon each reboot, Windows 7 may delete all System Restore Points.
This issue can occur if the system paging file is highly fragmented.
The resolution to this issue is to disable, delete and then recreate the paging file. To do this, carry out the following steps:
1. Right-click on Computer icon on Desktop and select Properties (or press WIN + Pause/Break keys). Now click on Advanced system settings link in left side pane (You can open it directly by giving sysdm.cpl command in RUN or start menu search box). Now click on Settings button in Performance section.
2. Now go to Advanced tab and click on Change... button under Virtual memory section.
3. Uncheck "Automatically manage paging file size for all drives" option if enabled.
4. Now select C: drive from the list and select the radio button labelled 'No paging file', then click the Set button.
5. Click Ok button and reboot your system.
6. After restart, delete 'pagefile.sys' from the root of C: drive. Please note that pagefile.sys is a hidden file and is not visible until you set the folder option to view hidden files.
7. Defragment C: drive by providing defrag /h c: command in Command Prompt.
8. Re-enable the paging file by following steps 1-3 above.
9. After selecting drive C: in the list, select the radio button for 'System managed size' and click Set.
10. Click Ok button and reboot your system.
