Today I will teach you how to solve the access denied error you get when you access "Windows.old" folder on your drive, usually this folder is created after installing windows over windows or after upgrading, it contains your old documents, desktop and programs.
This fix apply to:
Windows xp (32bit-64bit)
Windows Vista (32bit-64bit)
Windows 7 (32bit-64bit)
If you tried it in another version like win 89 or else let me know even I know it won’t apply as permittions was too weak those days.
Ok lets get started, first go to any windows explorer windows "I don't mean internet explorer but any window with files view", click on tools at the to if it's not shown like on windows 7 just press ALT and it will appear.
Click the "folder options" tab and then scroll down until you find "Use sharing wizard" or in xp and vista you will find Advanced > Use simple sharing and uncheck that and click Apply > OK.
Now go to your C: and where ever Windows.old right click it and > Properties then go to permittions tab, now you will be able to see the permittion options because we disabled simple sharing.
On security window click on Administrators and in the check boxes right after it check "full control", click Apply > OK.
now wait until it apply the new permittion to all your files, it could take hours if you have lot of files, but when it's done you will be able to access all of your files.
If it didn't work and still say the same don't worry just type in the address bar "C:\Windows.old" manually and hit enter, to get red of this just restart your comp to refresh permittions.
Glad to be your life saver, enjoy and congratulations on getting your files back.
