Remove unnecessary programs

Some programs have a delayed start and may cause the error 0x40000015 to appear several minutes or hours after starting without giving a reason.

• The ideal solution in this case is to activate the programs one by one, restart the device after each change, and determine when the error occurred, which should indicate the root cause of the problem. If the error persists even after a clean boot, the most likely cause is irreparable damage to the operating system. In this case, you need to reinstall it.
