Hi shashi1223, Since the issue occurs recently, please first try restoring the system to the date before the issue first occurred using System Restore to see if the issue can be resolved. If the issue persists, please try the following suggestions to see if the issue can be resolved. Use ShellExView to disable third party extension of Windows Explorer ========= 1. Download ShellExView v1.41 from the following link http://www.nirsoft.net/utils/shexview.zip Please Note: The third-party product discussed here is manufactured by a company that is independent of Microsoft. We make no warranty, implied or otherwise, regarding this product's performance or reliability. 2. Right-click the "shexview.zip" file, select "Extract All", the Extraction Wizard will prompt. 3. Click Next, input "C:\ShellExView" (without the quotation marks) in the "Files will be extracted to this directory" textbox. 4. Click Next and click Finnish. 5. Open the "C:\ShellExView" folder and double-click the "shexview.exe" file. It will scan the registry for all the shell extensions. 6. Select all the non-Microsoft extensions in pink by press "Ctrl" in the keyboard. 7. Click the "Disable Selected Items" on the toolbar and click Yes. 8. Restart your computer and check if the issue is resolved. However, if the issue persists, please test the issue in Clean Boot. If the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue. Reset Internet Explorer (IE) can also be helpful. To do this, please refer to How to reset Internet Explorer settings. In addition, you also can see if the issue occurs in a new user account with Administrator privileges. Also, please let me know if you used the Bitlocker encryption or adjust the user privileges using group policy editor? Regards, Linda
